bubble detecting sensor.

kurtisja
kurtisja over 11 years ago

Im looking for a sensor which can detect the presence of gas in a liquid line.

 

The scope of the sensor is to be used in a wine dispensing system. My hope is when the sensor detects a gas bubble in the line, it can shut off the flow, or lack thereof, of liquid.

 

Do you stock anything which may be able to achieve this desired outcome?

 

Ive been led to believe some type of optical or proximity sensor may be able to achieve this.

 

Thanks for your time.

    You could try using a laser pointer shining through your clear tube at an angle, onto a surface a few inches away. See if the spot on the surface shifts when a bubble is in the laser beam. If it does shift, then a simple light detector at the spot location will detect the bubble.

    Another method is to put small metal plates on each side of the tube - the capacitance between the plates will change when there is a bubble between the plates. You can buy commercial sensors that use this principle.

    Newark/element14 carry several Optek optical sensors that can detect liquids in tubes for $5 - $8.

    such as:
